Does he really want this baby?

Taryn
I found out I was pregnant 3 days after my fiancé, baby's daddy, left for AIT with the military. I spent the entire first trimester by myself, and while he was away at Fort Lee he seemed so excited. He talked about the baby, and plans, and how he was so happy. He came home recently and moved in with me, but now it seems like everything has changed. He changes the subject when it comes to baby or the future, he doesn't even really acknowledge that I'm pregnant. 
It hurts me. I love this baby so much, I don't understand why he doesn't even seem to want it. What do I do? This is my first baby. Am I gonna be raising him or her on my own?
